Improvement in heating-stoves and fubnaces

l Be it l'inown that I, WILLIAM C. GO0GI.NS, o fuPortlandyin the vcounty of Cumberland, and State of Maine, I have invented a new and useful Improved Furnace and Stove; and I hereby declare the following to be a full,

WILLIAM c'.v coociNs. or PORTLAND, MAINE.

clear, and exact descriptionY thereof, which will enable others to-makc and use my invention, reference being had tothe accompanying drawings, forming. part of this specification, in vvhich-`` Figure 1 shows a vertical section of my invention.4

Figure2 is a transverse'section of the same.

The object ofniy invention is the production of a heating-apparatus, by means of which heat may not only be thrown out into an apartment in which the heater may be placed, but-also an increased quantity created, in

. order to be conducted into other apartments, in the manner in which rooms are commonly heated by furnaces,

that is, conducted away from the. heating-apparatus by means of tubesor pipes.

In furnaces of the ordinary construction, a re-pot is generally placed in or nearthe centre, and this is surrounded at some distance by a metal casing or covering. Around this inner casing, and somewhat removed therefrom, is another. Between these two casings the aix-,being heated by the lire in the fire-pot, and thus rarefied, passes oifthrongh the proper tubes conducting to the rooms which the furnace is designed to warm. By such an arrangement, itwill-be understood that one side of the body of air. thusemployed is, while being heated, exposed to a comparatively cool surface-of metalto wit, the exterior casing or envelope of the "furnace- :One object of my invention is to sofa-rrange the construction of the furnace that a portion, at least, of the air heated by the iire in the furnace, shall be subjected to contact withno cooling inliuence whatsoever, while Y in the furnace,^but'shall be directly surrounded bythe fire in the same. i

v.To accomplish this, I pass directly throughl the furnace, from bottom to top, an air-tube, which admits the air at the bottom, and, as it becomes heated, leads it-away from the furnace, after having been conducted through said tube, through the middle of the fire. a, in iignl, shows this central tube or air-passage, leading from the bottom to the top ofthe furnace, and prepared at the top. to receive additional 'tubing or piping, to conduct the heated air furthenas'may be desired. t shows a cylindrical {ire-pot, surrounding lthe central tube, and c shows the grates at. th`e-botton1 thereof.

Thus it will he seen 4that thecentral air-tubea is entirely surrounded bythe iire in the pot b, and that air, entering the tube 'atfthe bottom, d, is brought in contact with no cooling surface until it passes from within the furnace.- This arrangement both increases the intensity of theheat, and, as a consequence, the power of the air rising therefrom to affect the, tempemrature'of distant apartments.

eshows the exterior envelope of the furnace, between which' and the fire-pot 6 there is the'space f, as is common, and from which pipes may. lead in the ordinary manner. y shows the doors, which, for convenience,

may be made upon opposite sides, as the fuel must be introduced all around-the 'central tube a. It shows the ash-pit of the furnace, encircling'the bottom of the air-tube a, in a manner similar to that in which the re-pot does the upper pOrtionsthereOf. shows the doors of the ash-pit. .The grates c are semicircular in form, 'divided into two 4Imr.ts,vvhich work separately, and may be tipped ori turned upon pivots k, when it is desired to remove the contents of there-pot 5. These grates are also supported at m.

By drawing out the handles or pivots Jn, `somewhat in the direction of the arrcrjs, the grates may bc tipped up edgewise, but', when pushed back, vthe grates pass for a short distanecnn'd'er the rim 1 in the bottom of the -iire-pot, and are then prevented from inclining or tipping.

' The central tube d is especially convenient forv thearrangement of a. means of impartingthe necessary degree of moisture to the air whichis heatediinfitQfor, by placing a dish, containing water, beneath the furnace under the lower aperture dof the central tube a, sudicient vapor will be created by the heat, and will be carried into the tubeby the current of airy' It is-apparent that various forms may be given to the tube but a conical shape is conceived to be the best ndmitting,.usit does, a large quantity of air atvthebottom. v

' I do not claim the tube a by itself, forit has vbeen used before; neither do I claim the tube with a watertank underneath it, which tank is opened or elosedby a valve operated by the entrance or exit of air, set forth in patent to J. Johnson, et al., No. 12,758, April 24, 1855.

Myinventon has in View the creation of :m increased amount of heat bythe combination of the tubeaand Iche common air-chambers j". It also` present-s increased convenience in lon-ding, by reason of the doors g, nml in'eleansing, by reason ofthe semicircular gratas c, ash-pt L, and doors z'.

By this arrangement of the tube aand the common ar-chambersf, increase of heat and economy of fuel may be attained.

Disclaiming the separate use of' -any of the devices above described, what I do claim, and desire to secure by Letters Patent, is-

The combination and arrangemcntbf the tube a, ar-chambersf, doors g, semicircular tipping-grottes c, and

asb-pitl lz, in a heating-furnace, substantially as and for the purpose set forth.
